Below is our expansive gallery and directory featuring flowers that start with “G”. It’s easy to understand why the Gentian flower is much-loved. If there’s a reason to it, its genuinely deep blue color certainly works to captivate the beholder.
This showy flower with five petals in the shape of a trumpet also appears like it’s sitting on top of its basal foliage. Reaching only about 4” tall, it spreads out as ground-cover and forms a mat about 6” wide, adding beauty to the already picturesque landscapes of the European alpine grasslands, meadows and forests where this flower is commonly spotted.
